catalyst for the promotion of additionreactions to epoxide electrophiles. Synthesis and evaluation of 6 revealed it to be a powerful catalyst for the addition of 1,2-dimethylindole to styrene oxide under conditions in which simple N,N-bis-aryl ureas and thioureas (including 1) are inactive. Subsequent studies determined 6 to be compatible with a range of indole and epoxide substrates (including (E)-stilbene
